Abstract
By means of continuous weighing method was investigated the kinetics of the interaction of sintered composite on the base of aluminium nitride with the molten potassium cryolite with cryolite ration (CR) 1,3 at temperatures of 700–800 °C. There was specified that at temperature 700 °C composite practically did not exposed to melt impact. Materials interact with molten salt through the stage of its oxidation in the melt of oxygen. At this, takes place besides merging of originally presented in material of oxygen-containing impurities. In the absence of an oxidizer and at concentration of dissolved in cryolite alumina, close to saturation, interaction of sintered aluminium nitride with examined melt did not observed.
